Abstract

This paper presents a temporal analysis of the relation between urbanized area growth and changes in the hydrological balance on the studied area, observing alterations in runoff and losses by infiltration in four neighbourhoods located in the city of Umuarama-PR, namely Jardim Bela Vista, Jardim Colibri, Jardim Yonezu and Parque San Remo I and II. This temporal analysis was made from three scenarios, representing the past (2004), the present (2013) and the future (projection), the area was divided into 26 blocks (sub-catchments) and was used the hydrological model SWMM 5:00:22 (Storm Water Management Model) to generate results such as the flow reaching at the receiver rainwater drainage channel, losses of the volume precipitated by infiltration into the soil - using a project precipitation with return period (Rp) of 3 years. The study area was analyzed as a whole and also individually, block by block. This paper draws attention to the issue of urban planning in the growth of cities and their social function, taking into account the identity of the place of study as well as environmental quality.
